Hi, linux-ide: We have a workstation with a dual-core Pentium 4 3.4 Ghz processor that started to panic last Friday. The machine stays up for 15 minutes to a few hours, then it panics again. We suspect a hardware problem, but I'd like to ask here whether there's newer libata or other code that fixes the panic. I've seen two panics since I heard about the problem and the stack trace each time has been: Badness in i8042_panic_blink at drivers/input/serio/i8042.c:988 i8042_panic_blink +0x188/0x1a0 panic +0xc/0x147 die +0x164/0x16b vprintk +0x136/0x149 do_page_fault +0x0/0x5b6 do_page_fault +0x3f0/0x5b6 ata_to_sense_error +0x40/0x299 [libata] recalc_task_prio +0x128/0x133 activate_task +0x88/0x95 try_to_wakeup +0x222/0x22d autoremove_wake_function +0xd/0x2d __wake_up_common +0x36/0x51 do_page_fault +0x0/0x5b6 error_code + 0x2f/0x38 ata_to_sense_error +0x40/0x299 [libata] ata_scsi_qc_complete +0x17/0x2d [libata] ata_qc_complete +0x6b/0x7b [libata] ahci_interrupt +0x100/0x151 [ahci] handle_IRQ_event +0x25/0x4f do_IRQ +0xb0/0x130 common_interrupt +0x18/0x20 unix_detach_fds +0x2e/0x31 (Anything confusing about the stack might be due to the fact that I wrote it down by hand.) The kernel came with RedHat EL 4.0. Uname -r shows 2.6.9-5.ELsmp. In case it's useful, here is output from dmesg.
libata has seen a LOT of updates during last few months. Can you try 2.6.17.7 or 2.6.18-rc2?
